The amplitude of lepton-pair production in relativistic ion collisions beyond the perturbative theory
A. N. Sissakian, A. V. Tarasov, H. T. Torosyan +1
We investigate the structure of some first terms of Watson series representing the amplitude of lepton-pair production in the ion collisions. It is shown that infrared instabilitie…

Nuclear Shadowing in DIS at Moderately Small
J. Raufeisen, A. V. Tarasov, O. O. Voskresenskaya
In the rest frame of the nucleus, shadowing is due to hadronic fluctuations of the incoming virtual photon, which interact with the nucleons. We expand these fluctuations in a basi…

The eikonal approach to calculation of the multiphoton exchange contributions to the total cross sections of π^+pi^- atom interaction with ordinary atoms
L. Afanasyev, O. Voskresenskaya
The total cross sections of interaction of relativistic π^+π^- atom with ordinary atoms are obtained in the eikonal approach, which takes into consideration all multiphoton exchang…
